Brian,
You might try going into the KAT3 menu and go through the L1-L8 and
C1-C8 settings to hear the relays click with each selection.
If all the relays are working, you should be able to do a check on the
health of the inductors and capacitors using a method similar to that
shown for the KAT100 in the right column of page 35 - manually select
the inductors starting with L1 and see what the SWR is on a high band.
With each other inductor, the SWR should increase. Change to a lower
band if the SWR gets too high to indicate (highest is 9.9). Do the same
for the capacitors.
I have not tried this technique with the KAT3 (but it should work) - I
have used it with the KAT100 and the KAT2.

Hi Don,
Further insight needed.
John and I have looked into the 80M tuner strangeness problem further.
We both have qualitatively seen the same thing. It is related to
trying to tune Z's that are on the order of 25-30 ohms on 160M/80M.
